Rosin (colophony) allergy

What is rosin and where is it found?

Rosin, also known as colophony, is the sap or sticky substance that comes
from pine and spruce trees. Its "stickiness" lends itself to being used in a
wide range of products. The table below shows only some of the many products
that contain rosin we may come into contact with either at home or at work.

What are the reactions to rosin allergy?

Reactions to contact with rosin in an allergic individual include acute
allergic
contact dermatitis and asthma. In allergic contact dermatitis the
dermatitis tends to occur 1-3 days after contact with rosin, although
occasionally reactions can appear within 24 hours or even more than a week
after exposure. The dermatitis tends to be confined to the site of contact
with rosin (e.g. hands and forearms after carrying pine wood, although the
face may also be involved). Initially the skin becomes red and inflamed, and
is generally itchy. As the reaction progresses it may blister and become
even more intensely itchy. If exposure is continued, the dermatitis may
eventually become chronic with thickened, lichenified skin.
